Constant exotropia is uncommon during the first year of life.We investigated characteristics, surgical outcome and associated ocular abnormalities in patients who had an exodeviation during the first year of life. The charts of 18 patients who were diagnosed as congenital exotropia before 1 year old were reviewed.We etrospectively analyzed 10 healthy patients who did not have associated systemic or ocular abnormalities and were followed for at least 3 months after surgery. The mean follow-up period was 1.2 years[range, 3 months to 3.5 years]and all of them had an exodeviation of 25 prism diopter[PD]or more[mean, 37.5PD, SD 10.6PD].Preoperative DVD and inferior oblique muscle overaction were found in 1 patient respectively. Surgery was performed in 9 cases and botulinum toxin was injected in 1 case.Seven patients[70%]showed stable alignment within 10PD with one operation and one patient required reoperation.Postoperative dissociated vertical deviation and inferior oblique muscle overaction were found in each 1 patients. Congenital exotropia has large deviation and may be associated with inferior oblique muscle overaction or dissociated vertical deviation as infantile esotropia and has stable alignment with single operation.But unlike infan-tile esotropia, nystagmus is extremely rare.

Thirty one children with horizontal strabismus in age less than 10 years were treated with botulinum toxin type A(Botox) injection of extraocular muscles. We have analyzed the effects and complications of injection in twenty five patients for whom follow-up of 3 months or more was available. Preinjection alignment was 25+/-11 prism diopter(PD) in exotropia and 35+/-10PD in esotropia. The average time of maximal effect was 1 week after injection and the average time to achieve orthotropia 2 to 3 months after injection. At three months after injection, the alignments in fifteen patients(60%) were 10 prism diopter(PD) or less, in eight between 10 and 20PD, and in two more than 20PD. Success rate was high when limitation of eye movement was obvious(> OR = -2) at 1 week after injection. The most common complications were ptosis presented in fifteen patients(60%), subconjucntival hemorrhage in eight, abnormal head position in seven, vertical strabismus in seven and disorientation in one. Initial injection of botulinum toxin showed poorer results compared to surgery in childhood horizontal strabismus but did not show severe complications except undercorrection. Toxin injection can be an alternative choice of strabismus management but more prolonged follow-up will be needed.

Background: Stomach cancer is the most commonly diagnosed malignant tumor in Korea. Early detection by mass screening very important to increase survival rate of stomach cancer, because the prognosis of early gastric cancer is excellent, and specific symptoms and physical findings are rare with early gastric cancer. Methed: 1865 car manufacturing company employees were examinined by gastrofiberscopy at a dispensary of the company from May 6, l992 to July 13, 1992. Results: 1. Number of cases with normal finding was 1262(67.7%), gastritis 422(22.6%), gastric ulcer 47(2.5%), gasrtric cancer 4(0.2%), duodenitis 39(2.1%), duodenal ulcer 63(3.4%), combined ulcer(gastric & duodenal) 2(0.1%,), post operative state 6(0.3%), and others 4(0.3%) in total 1865 examinees. 2. Of 422 cases with gastritis, cases with superficial gastritis were 171 (9.2%), atrophic gastritis 138(7.4%), erosive gastritis 94(5.0%) and hemorrhagic gastritis 19(1.0%). 3. Of 4 cases with stomach cancer, 1 case was advanced stomach cancer and 3 cases were early gastric cancer(two cases of IIc and one case of IIc+III) by macroscopic classification. Conclusion: Mass screening provides an excellent opportunity to detect gastric cancer in populations without symytoms or with nonspecific symptoms. It should be recommended to undergo screening exam for high risk group of stomach cancer.

A total of 377 pregnant women, 43 pelvic tumor patients and 80 of multiphysic health center persons as controls were examined by indirect latex agglutination test in order to evaluate Toxoplasma antibody titers at Kang-Nam St. Mary's Hospital in Seoul. Throughout this survey, 1:32 or more titers of diluted sera were regarded as positive. The 337 samples of test sera in pregnant women showed negatives in 319 cases (84.6 percent), 1:2 in 44 cases (11.7 percent), 1:4 in 9 cases (2.4 percent), 1:8 in 2 cases (0.5 percent), 1:16 in 1 case (0.3 percent) and 1:32 in 2 cases (0.5 percent) respectively. The 43 samples of test sera in pelvic tumor patients showed negatives in 29 cases (67.4 percent), 1:2 in 8 cases (18.6 percent), 1:4 in 1 case (2.3 percent), 1:16 in 2 cases (4.7 percent), 1:32 in 1 case (2.3 percent) and 1:128 in 2 cases (4.7 percent). The 80 samples of test sera in multiphysic health center persons as controls negatives in 56 cases (70.0 percent), 1:2 in 19 cases (23.8 percent), 1:4 in 3 cases (3.8 percent), 1:8 in 1 case (1.3 percent) and 1:128 in 1 case (1.3 percent). Among total 420 study cases, 5 cases (1.2 percent) showed positives , and they were 2 cases (0.5 percent) of pregnant women and 3 cases (7.0 percent) of pelvic tumor patients. One case (1.3 percent) out of 80 control sera showed positive result.

Optic disc can be analyzed with computerized optic nerve head analyzer or confocal scanning laser ophthalmoscope because optic disc has 3-dimensional structure. But the great cost of these instruments makes their utility for the average ophthalmologist unlikely. We measured optic discs with personal computer and stereophotograph and report as follows. Seventy-six optic discs of 76 normal subjects[61 men, 15 women; mean age: 25.5 years] were evaluated by stereoscopic optic disc photography. The area and length were measured by a computer graphic program and converted to absolute unit with Littmann's formula. The mean vertical disc diameter[1.94+/-0.24 mm], the mean horizontal disc diameter[1.67+/-0.23 mm], the mean vertical cup diameter[1.03+/-0.20 mm], the mean horizontal cup diameter[0.96+/-0.19 mm], the mean disc area[2.64+/-0.62 mm2], the mean disc circumference length[5.84+/-0.67 mm], the mean cup area[0.82+/-0.30 mm2], the mean cup base area[0.22+/-0.17 mm2], the mean cup slope area[0.60+/-0.21 mm2] and the mean rim area[1.82+/-0.41 mm2] were evaluated. The new technique to measure optic disc with stereophotograph and personal computer is thought to be a useful method to understand threedimensional structure of optic disc with relatively simple instruments.

We conducted a prospective study to compare MMC subconjunctival injection with MMC soaking for surgical outcome and postoperative complications as an adjunct to trabeculectomy in eyes with glaucoma. Eleven patients with bilateral glaucoma had undergone primary trabeculectomy with adjunctive subconjunctival mitomycin-C injection in one eye[Group I] and primary trabeculectomy with subconjunctival mitomycin-C soaking in the other eye[Group II]. Minimal follow-up period was 6 months and mean follow-up period was 12.8 months. Preoperative mean IOP was 35+/-10.9 mmHg in the group Iand 33+/-14.4 mmHg in the group II, and there was no statistical significance. Postoperative mean IOP at 1, 3, 6 months were 13+/-2.3, 13+/-3.1, 13.6+/-2.9 mmHg in the group I, and 11.3+/-3.3, 12.2+/-3.4, 12.9+/-2.7 mmHg in the group IIand no statistical significance. Each of ten eyes[91%] in both groups achieved intraocular pressure of less than 21 mmHg and good bleb formation without any medication. Postoperative complications were transient hyphema[18% in the group I, 9% in the group II], cystic bleb[9% in the group I, 27% in the group II] and shallow anterior chamber[9% in the group II]. Postoperative corneal endothelial cell density per square millimeter averaged 2, 221+/-306/mm2[mean+/-standard deviation] in the group I and 2, 195+/-272/mm2in the group II and there was no statistical significance. The rates of surgical success and postoperative complications were similiar in the two groups. Subconjunctival injection has similar effect to soaking method. This method enables us to have accurate control of concentration and amount of MMC, and thereby reduces complications and improves surgical outcomes in trabeculectomy.

PURPOSE: To compare conventional laser peripheral iridotomy (LPI) and LPI combined with laser peripheral iridoplasty in eyes with primary angle closure suspect (PACS) by assessment of anterior chamber dimensional changes using a Pentacam. METHODS: Forty-eight eyes of 24 subjects with bilateral PACS were recruited consecutively. Each eye was randomly allocated to treatment with conventional LPI, argon LPI only, or LPI plus iridoplasty, which consisted of simultaneous argon LPI and peripheral iridoplasty. Anterior chamber measurements were performed on each eye using a Pentacam, both before and after treatment. Mean anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle were measured, and topographic ACD analysis was performed. Results were compared between the two treatment groups. RESULTS: After treatment with either conventional LPI or LPI plus iridoplasty, the mean ACD and ACV increased significantly. Topographic ACD analysis revealed that the mid-to-peripheral ACD increase was significantly greater in the LPI plus iridoplasty group than in eyes treated with conventional LPI. Intraocular pressure changes and post-LPI complications did not differ between the groups. CONCLUSIONS: Compared with conventional LPI, our study showed that LPI plus iridoplasty improved the mid-to-peripheral ACD increase. This procedure may have a role as an adjunct for reducing angle closure by simultaneously eliminating pupillary and non-pupillary block components.

We expierenced two cases of intradural verteral artery dissecting aneurysms. The presenting symptom was subarachnoid hemorrhage in one case and ischemic symptom in the other. The preoperative angiographic finding typically showed fusiform dilatation and proximal and/or distal narrowing of the affected artery. In one case, the vertebral artery was clipped distal to the PICA and in the other case trapping was performed through the extreme lateral transcondylar approaches. This approach permits a control of the aneurysm through the direct view of whole length of the vertebral artery, lower cranial nerves and ventral brain stem. In order to obtain ample view and to save the lower cranial nerves and perforating vessels, jugular tubercle should be sufficiently drilled out. Postoperitive neurological outcomes were favorable except mild hoarseness for some period in trapping case.
